Installation Considerations

RECOMMENDED AMPLIFIER POWER

For satisfactory performance, we recommend using a surround ampliﬁer with a power rating of 20-150 watts for the Pro770FX. We recommend an ampliﬁer power rating of to 20-200 watts for the Pro870FX. Most loudspeakers are not damaged by large ampliﬁers, but rather by small ampliﬁers. If your system is playing loud music, a small ampliﬁer will run out of power very quickly and can create damaging “clipping” distortions. A more powerful ampliﬁer will play at the same volume without distorting. See OPERATION on page 9 for more information about ampliﬁer clipping distortion.

LOUDSPEAKER WIRE

Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or ampliﬁer. For most applications, we recommend using 16-gauge wire. For wiring runs longer than 80 feet, we recommend 14-gauge wire. Every StageFront Pro loudspeaker features gold-plated, ﬁve-way binding posts that will accommodate up to 12-gauge wire directly. Larger sizes can be accommodated via pin connectors.

NOTE: THESE FIVE-WAY BINDING POSTS CAN BE CONNECTED IN SEVERAL DIFFERENT WAYS (E.G., BANANA PLUGS, SPADE TERMINALS, AND DIRECT WIRING).

When running wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3) to protect the wire and to meet local electrical and ﬁre codes. In some areas, conduit is also required. For a trouble-free installation, low-voltage wire such as loudspeaker wire must be run in accordance with the National Electrical Code and any applicable provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket, or type of conduit to use, consult a professional audio/video installer, building contractor, or the local building and inspection department.

TECH TIP

Wire size is expressed by its AWG (American Wire Gauge) number – the lower the number, the larger the wire. For example, 12 AWG is physically larger than 14 AWG.
